This is a docs-only seed. Tomorrow's session will add the actual Go
source: main.go, internal/rpc/client.go (JSON-RPC + cookie auth),
internal/chain/, internal/explorer/ (handlers), and internal/view/
(templates + static assets, embed.FS).
Until then this commit gives the repo its shape: README with the full
design, config example with all knobs, MIT license to match the
chain, and a .gitignore for Go build artifacts.
